Re: Broad area of disturbed weather in the Western Caribbean Sea
More on the 51 member 0Z EPS, which was much more active than any earlier run, along with Oct. 1-10 genesis climo:
13 H landfalls on FL (in addition to several TS hits):
- 5 Panhandle
- 5 Apalachicola to N of Tampa (includes Big Bend)
- 2 Tampa-Sarasota area
- 1 south tip
Not to be ignored, it also has 3 landfalls on LA (in addition to 2 TSs):
- 1 LA/MS border on 10/10
- 1 W LA 10/13
- 1 central LA 10/15
Tracks of TC with genesis 10/1-10 1851-2015:
https://www.nhc.noaa.gov/climo/images/oct_1_10.png
Favors a NE mover over FL but a significant 2nd max (just like the 0Z EPS has) moving N to NE over LA, especially central and eastern LA.

Re: Broad area of disturbed weather in the Western Caribbean Sea
Looks like that LLC is starting to pop with convection, this might slowly organize this weekend.

Re: Broad area of disturbed weather in the Western Caribbean Sea
Out of an abundance of caution I've activated the patented Tampa Bay hurricane shield. We're closing in on a 100 year streak (1921) absent a major hurricane and we've just come too far to give up now. On a slightly more serious note let's hope the persistent shear keeps whatever eventually comes of this in check. I'm all in for some tropical storm party weather but tall trees (which I love) really temper my enthusiasm for anything more than that..

Re: Broad area of disturbed weather in the Western Caribbean Sea
I see our vort from yesterday has grown quite a bit.
A couple of quick look scenarios.
1. the LLC begins to move more S then Se back over water in response to convection that appears to be building between it and that larger convective mass.
2. the LLC dies over land and then a secondary circ develops near the large convective mass.

If there is nothing before... then just ask

Does seem that the small LLC is caught in a broader overall gyre, given time and over the water it should slowly consolidate and if shear relaxes any at all then all bets are off.

Yeah, assuming we get a solid llc with continuous convection shear should begin to relax some. we will see throughout today what actually happens with the surface consolidation.

Re: Broad area of disturbed weather in the Western Caribbean Sea
Once again the GFS is south of all the other models hence no development

Re: Broad area of disturbed weather in the Western Caribbean Sea
After taking a closer look at everything. I would not be surprised if another circ forms North of San Andres Island over the next few hours especially if the current llc moves inland and spins down and if convection continues to build east of Honduras.

Re: Broad area of disturbed weather in the Western Caribbean Sea
AS strange as it is .. the CMC is the only model that has stuck to the same solution this entire time. and the 00z euro now has a very similar solution.
unsure why this is not an invest yet. but I imagine it will coming today at some point.

ICON is on board with the 00z EUro, and cmc now.

Re: Broad area of disturbed weather in the Western Caribbean Sea
CMC ridge is weaker and cold front is stronger than the GFS, GFS ridge is stronger and the cold front is weaker lol should be fun to watch.

Re: Broad area of disturbed weather in the Western Caribbean Sea
Even though there is a ton of shear over the NW Caribbean and S GOM today, the 12Z GFS run shows this shear lessening quite a bit by 130 hours. (And still fails to develop it, so there you go).

I must say the front can wait, damage from a hurricane is not cool when you want some cooler days
